To all whom 'it may concern: 7

Be it known that I, CHARLES JAQUET, a subject of the German Emperor, residing at Strassburg-Konigshofen, Alsace, German Empire, have invented certain new and useful Improvements in Grain-Reducing Machines, of which the following is a specification. 7

My invention relates to grain reducing machinery of that class in which the grain being treated is reduced by the mutual friction of the groats and by their being acted upon by blades or vanes, while the outlet for the reduced material serves to retard more or less the flow of grain during such treatment in the machine.

The purpose of my invention is to render the outflow of the material uniform at all parts of the exit, and this Ieffect by somounting one of the two plates or walls which present the discharge-gap between them that it can swing back relatively to the complementary plate.

In the accompanying'drawing Figure 1 is a longitudinal section through a machine constructed according to my invention. Fig. 2 is a plan and part section on the line AB' of r Fig. 4. Fig. 3 is an end elevation. Fig. 4 is a cross-section on the line 'CD of Fig. 1. Fig. 5 is a cross section on the plane indicated by the broken line E in Fig. 1.

Referring specifically to the drawing, 1) indicates a cylinder in which is journaled a screw-conveyer, c, driven from any suitable power applied, for instance, through a pulley, 1', or the like. At one end as at q, the cylinder is screw-threaded to receive an annular, dish-shaped plate, which with asimilarly shaped plate, '5, forms a chamber, d.

Secured upon the shaft of the conveyer 0, within the chamber (1, are blades, e, which, when rotated, act in conjunction with the inner surfaces of plates, f, i, upon the grain, fed into a hopper, p, and through the conveyer into chamber (Z. After the grain has been thus acted upon by the blades as stated, it is discharged from chamber (1," through the space g, between the edges of plates f and i, into a passage, 71.,and thence to any suitable receptacle. The plate f is adjustable, by means of its screw thread, but always in a plane at a, right angle to the shaft of conveyer, '0, but plate '5 ispivoted below its lower edge, upon a shaft or pin, 7c, so that it may be moved in the arc of a circle of which said shaft, 7c, is a center to or from the vertically placed plate, f.

In orderthat the plate '5 may be yieldingly held in position, and may give under pressure of the grain in chamber d, it is connected, nearits upper end by a link, 25, to one arm of an elbow lever, s, pivoted on shaft, Z, the

other arm carrying a weight, m, by the adjustment of which the pressure of plate 11 towardplatef is regulated. By virtue of its pivotal support on shaft 7c, when the plate 'i is pressed by the grain away from plate f, the gap or space g will increase in width more rapidly at the top than at the bottom, and when the pressure is decreased, and the weight m forces the plate '1' toward the plate f, the reverse will occur.

The operation may be described as follows: The grain is charged into the machine through the hopper and is fed along the cylinder b by the conveyer c, in the direction of the arrow a, until it reaches the chamber (2 constituted by the two plates f '5. Here it is acted-upon by the blades e, mounted on the conveyer shaft, and is forced through the gap 9 between the edges of the plates f '11, into the passage 7 by which it leaves the machine. It is obvious that the grain at the bottom part of the gap 9 will run out more readily than the grain at the upper half of the gap. In order to insure uniform exit at all arts by rendering the gap wider at the to t e plate 1' is mounted to swing on a shaft so that it can automatically retreat more or less from the stationary plate f, which is screwed into the end of the cylinder casing with capability of adjustment. The oscillating late i is loaded by means of a weight 'm, w ose lever is affixed to a shaft Z, to a fixed collar on which the plate '2', is linked. The weight m forces the cover t toward the plate f, but allows the former to yield when a large quantity of grain is to pass through the machine with uniform pressure.

In order to admit of the gap g being adjusted to suit the quantity of material being dealt with, the shaft is is mounted in sliding bearings a.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a grain reducing machine, the combination with the frame of the machine having a horizontal conveyer chamber formed therein, of a stationary plate at the end of said chamber, and a movable plate, the two second )late opposite the first forming thereplates bein vertically arranged opposite each other to form a blade chamber and having a vertical space between their edges for the outflow of grain, and means for adjusting the movable plate whereby its upper edge is moved farther than its lower edge away from or toward the corresponding edge of the stationary plate, thus forininq an outlet gradually increasing in ca acity from bottom to top, substantially as escribed.

2. 1n a grain reducnig machine, the combination with the frame of the machine having a horizontal conveyer cylinder formed thereln, of a vertical stationary plate, and a with a lade chamber, at the outlet of the conveyer cylinder, the second plate being pivotally mounted at its lower edge whereby it may be swung away from the first plate to cause the space between the two plates to become wider at the top than at the bottom, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES JAQUET.
